<p>
The <tt class="function">bisect()</tt> function is generally useful for categorizing
numeric data.  This example uses <tt class="function">bisect()</tt> to look up a
letter grade for an exam total (say) based on a set of ordered numeric
breakpoints: 85 and up is an `A', 75..84 is a `B', etc.

<p>
<div class="verbatim"><pre>
&gt;&gt;&gt; grades = "FEDCBA"
&gt;&gt;&gt; breakpoints = [30, 44, 66, 75, 85]
&gt;&gt;&gt; from bisect import bisect
&gt;&gt;&gt; def grade(total):
...           return grades[bisect(breakpoints, total)]
...
&gt;&gt;&gt; grade(66)
'C'
&gt;&gt;&gt; map(grade, [33, 99, 77, 44, 12, 88])
['E', 'A', 'B', 'D', 'F', 'A']
